SWITGH-TONGUE-HOLDING DEVICE.

Specification of Letters Patent. Patnted Nov. 30, 1920.

Application led July 2,` 1920. -Serial No. 363,516.

residing at Redford, in the county of Wayne invented certain. new anduseful Improvements in SwitclrTongue-Holdin Devices, of which thefollowing is a specification, reference being had therein to theaccompanying drawinos.

In my pending application Ser. No. 326,548, filed Sept. 26, 1919, thereis disclosed a novel retaining member or spring construction by which aswitch point or tongue may be positively held in an adjusted position,either with the switch point closed or opened, and since there is nointermediate and State of Michigan have j position for the switch point,derailments inactive so that it will constitute lockin means for aswitch point or tongue.V fit my installation it will thereforebepossible to lock a switch point in a set position with `no danger ofthe switch point becoming accidentally displaced by rolling stock contacting with the same. o

This invention also includes locking means and yieldable means for thearms `that may be set to hold the arms against movement.

The mechanical construction entering ijito my invention also permits ofa two-way snap switch point being converted into a Oneway snap switchpoint, and the construcj tion by which this and other features areattained will be hereinafter described and then claimed. j

Reference will now-be had to the drawings, wherein- Figure 1 is a planof an electricrailway switch provided with a switch tongue holdingdevice in accordance with my invention y Fig. 2 is a horizontalsectional view of a portion `of the switch mate showing the springhousing in plan with the cover thereof removed;

Fig.` 3 is a cross sectional view of the same with the cover in lace;

Fig. 4 `is a simi ar view showing the arrangement for `a one-way snapswitch tongue; y

Fig. 5 is a similar view illustrating a modification of the arrangementshown in Fig. 4; o

li`ig6 is a perspective view of a detached shim or spacer member, and

j Fig. 7 is a plan ofa housing containing a modified form of tongueholding device.`

In the drawing, the reference numerall denotes a conventional form ofswitch mate having a pivoted switch tongue 2 and the switch mate 1 isslotted, as at 3, and rovided with a chamber 4 for the depen ing lug 5,of the switch tongue 2, The side of the tongue 2 has an opening 6communicating with the chamber 4. 'and Jroviding clear-` ance for a rodor slide bari? nected to the lug 5 and provided with nuts 8, spacingsleeves 9 and a double conical shaped head 10, the head 10 beinginterposed between the confronting ends of the sleeves Q. and allvof theelements held assembled on the rod 7 and fixed relative to the lug 5 bythe nuts 8 on the ends of said rod.

Connected to the side of the switch mate 1, by screw bolts 11 or otherfastening means, is a rectangular housing l2 having a countersunkdetachable cover 13. In the housing 12, adjacent the outer wall thereof,is a vertical partition 14:` having angularly disposedend portions 15and the partition has its upper edge provided with slots 16. In one ofthe` slots 16 -is mounted a bolt 17 having a shimor spacer member 18 anda nut`19 for holding a one piece spring or resilient retaining member20. The shim, or spacer member has a concave face pro vid nga seat forthe spring 20 and said shim or spacer member is slotted, as at 2l, sothat it may be shifted down over the bolt 17 and clamped between thespring 20 and the partition" 14 by tightening the `nut 19 -of the bolt17.` Since the shim or spacer member 1S can be easily removed it ispossible to substitute other shims for that one shown to ive-positionthe spring on the bolt 17.

which is conksal arms for reglfllating the outward movement thereof.

2. Means as eharaeterlzed 1n clalm 1,

wherein said arms maybe locked against separation hy means supportedindependent ot said arms. f

3. Switch tongue holdin@ means comprising a head movable with the switchtongue opposed means engaging said head an adapted to yield to 'ermtsaid head to 10 move, and means for ocking sadfopposed v means againstany yielding movement.

In testimony whereof I aix my signatme in the presence of two Witnesses.
